We optimise diesel injectors and pumps

Bad Fuel

Poor fuel is an ever increasing problem in this country.

If you're doing a lot of travelling and buying fuel from lots of different suppliers you never know what you'll get.

A number of problems are common due to poor fuel quality such as:

  • Blocked or damaged injectors

  • Poorly set up or leaking fuel pumps

  • Poor filtration and engine damage

Blocked and Damaged Injectors

Poorly set up, blocked or damaged fuel injectors result in poor vaporisation of the fuel which leads to poor combustion which leads to fuel wastage and engine damage.

Your injectors are the heart of your engine. Without the correct spray pattern the diesel will not burn properly and your vehicle will under perform.

It is important to have your injectors serviced correctly or else everything you do after that will be just trying to correct this basic problem.

Poorly set up or leaking fuel pumps.

Due to increasingly poor fuel being available in Australia we have noticed a number of vehicles having problems with leaking injector pumps.

A number of dealerships have brought near new factory vehicles to us with these problems.

It's amazing how quickly poor fuel can damage an engine. Leaking injector pumps are one of our specialties and with some specialised techniques we have developed we have a 100% success rate in fixing the problem.

Some tips to avoid bad fuel and engine damage.

  1. Use only brand name fuel ie. Shell, Mobil, Caltex etc. Check with your garage regarding their supplier.

  2. Avoid using additives. Your engine was made to run on pure diesel.

  3. Change out your filter every 10,000km.

  4. Check you filters regularly. Our lucas/cav adaptor has a glass bowl which allows easy visual inspection of your fuel.

What to expect from a diesel service

  • A diesel service at Berrima takes a full day. The whole fuel injection system is set up so that your engine is running as it should be.

  • The injectors are removed and dismantled, then tested, repaired as necessary, then reassembled.

  • The pump timing, fuel loading, aneroid operation and turbo operation(where applicable) are adjusted to give the best possible performance. All within factory specs.

  • You can expect cleaner running and better performance from your vehicle after it's had the Berrima Diesel treatment.

  • The tappets are adjusted where needed.

  • You will notice improved fuel economy with a properly set up vehicle and you will get extended engine life.

  • The filter system (air and fuel) is checked. We can advise you on the best system for your individual needs.

  • All vehicles are fine tuned ON (and off) ROAD, where they run. Your vehicle is fine tuned for it's best performance potential under REAL LIFE conditions, NOT on a dyno! That's one reason why we are able to get your vehicle performing like no one else can.
